Meteor:尝试在/public 之外提供静态文件 [英] Meteor: Trying to serve a static file outside of /public

问题描述

TLDR;如何通过铁路由器提供静态文件?如果我将文件放在/public 中，它会绕过我可以在铁路由器中使用的所有钩子.

TLDR; How can one serve a static file through iron router? If I place a file in /public it bypasses all the hooks I could use in iron router.

长版:我需要将所有请求记录到图像文件中.具体来说，我想在每个请求中坚持到 Mongodb，例如来自 http://domain.com/cat.png?a=1&b=2.

Long version: I need to log all requests to an image file. Specifically I'd like to persist to Mongodb the querystring in every request such as 'a=1&b=2' from http://domain.com/cat.png?a=1&b=2.

我在 Meteor 中没有看到这样做的方法.但是我可以使用铁路由器挂钩，例如 params.query .除了/public 中的任何静态文件都由 Meteor 的处理程序提供服务，并绕过铁路由器.

I don't see a way of doing this in Meteor. But I could use the iron router hooks such as params.query . Except that any static files in /public get served by Meteor's handler, and bypasses iron router.

(我希望使用最新的 api.这里有很多关于流星 1.0 和 Ironrouter 前的帖子)

(I'm looking to use up to date apis. There are lots of posts here pre meteor 1.0 and pre ironrouter)

推荐答案

您可以使用 fs 来服务任何文件:

You can use fs to server any file:

Router.route('/static/:filename', function (){
  var fs = Npm.require('fs'),
      path = '/tmp/' + this.params.filename; // make sure to validate input here

  // read the file
  var chunk = fs.createReadStream(path);

  // prepare HTTP headers
  var headers = {}, // add Content-type, Content-Lenght etc. if you need
      statusCode = 200; // everything is OK, also could be 404, 500 etc.

  // out content of the file to the output stream
  this.response.writeHead(statusCode, headers);
  chunk.pipe(this.response);
});
